David, I have three of these but can only find one. It is relatively small: just 2= 6 rows on .3 inch centers with 50 pins per row. Also, quite a few pins around the perimeter are bent, some of them quite a bit. I think they could all be straightened out with a manual wrap tool. If you are still interested then = I will come up with a price for you. Alternatively, you could wait to see if = I can find the better/larger ones. -- Bob Ammerman RAm Systems -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of David Robertson Sent: Monday, October 15, 2012 6:57 AM To: Microcontroller discussion list - Public. Subject: [BUY] Wanted: wire wrap prototype board Hi everyone As part of my 7400 series logic CPU project I'm looking for one of these wire wrap boards like are shown at this link http://www.bigmessowires.com/2007/12/08/first-hardware/ I've had a look online, and there's a few on eBay, but they're all at ridiculously high prices - they're being sold as collectors' items or something. These things were made to be used! If anyone has and is willing to sell me one, or knows of a relatively cheap source of these, please reply. Thanks, David. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
